What is a “安全锤” (ānquán chuí) on a Chinese high-speed train?

Carriages on China’s high-speed rail typically carry a small red hammer mounted near the window. It is called the 安全锤 (ānquán chuí): 安全 (ānquán) means “safety” and 锤 (chuí) means “hammer.” In a real emergency, passengers use it to shatter the glass at the corners and use the window as an exit. The clip warns clearly: 这是应急用的，平时可不能碰 — “this is for emergencies; do not touch it normally.”

The word breaks down helpfully: 安 (ān, peaceful/safe) + 全 (quán, complete/whole) = safety; 锤 (chuí) = hammer. You see 安全 everywhere in China — 安全帽 (ānquán mào, hard hat), 安全带 (ānquán dài, seatbelt), 安全出口 (ānquán chūkǒu, emergency exit). The 安全锤 is a familiar fixture of Chinese public transport. The clip also explains the red-vs-green toilet indicator (红色代表有人，绿色代表没人) and the under-seat charging socket — a high-density vocabulary tour of a real high-speed train journey.
